:BLOWER FOR 'HUskINe MACHINES.

Application sied lepri-1 41s, '1925. Iseria-1 no. 24,113.

To 'all whom t may concern:

Be it known that I, GEORGE J. SOUJKUP, a citizen Vof the United States of America, residing at l/Vagner, in the county Of'Char'les Mix -and State of South Dakota, 'have 'invented certain new and useful Improvements `in Blowers for l'lusking Machineaof which the following is a specification.

This 'invention relates to new and usefull `improveniente in blowers 'for husking machines.

The primary object of the invention is the provision of an improved form Aof iblower for the box within which the husking 'rolls of a Corn husking lmachine operate.

A Lfurther object of the invention is'the pro-vision fof an adjustable Inozzle for athe type of blower above referred to.

'Other objects and advantages of the invention will be apparent lduring vthe course of the following description.

Tn fthe 'accompanying `drawings forming a part of-this specilicationandin l'whichflike numerals are employed Vto designate like parts throughout the same,

Figure l showsin sideelevationa'lblower and its dri-ving `mechanism mounted Eupon the "husking portion of `'a husking machine shown in dotted lines,

Figure 2 is a top plan view of the structure shown in Fig. 1,

Figure 3 is a top plan view of a modified form of blower,

Figure 4.- is a longitudinal vertical sectional view taken upon line IV-IV ofv Fig. 3,

Figure 5 is a transverse sectional view taken upon line V-V of Fig. 3,

Figure 6 is a transverse sectional view taken upon line VI-VI of Fig. 3, and

Figure 7 is a fragmentary longitudinal sectional view showing a flap valve structure and its adjusting and holding mecha.- nism.

ln the drawings, wherein for the purpose of illustration is shown the preferred embodiment of this invention, the numeral 5 designates the portion or box of a corn husking machine wherein the husking machine operates and which has a driven shaft 6 upon which it is to be understood a portion of the husking mechanism is carried, but not shown. This shaft 6 has loosely mounted thereon a sprocket wheel 7 having riding thereon a sprocket chain 8 which leads to a sprocket wheel 9 carried by the blower shaft 10 `mounted in the 'blower casing 1.1 which is supported by the brackets ulpon the husking 'box l5. The sprocket 'wheel 7 'is'seleotively connected to lthe 'husk- -ilng mechanism driven --shaft 6 bythe clutch structure 13 lwhich is shifted by the angular lever 14 mounted in the vbracket l5. The ffree end 16 of this lever 215 is normally actuated by the spring 17 into a 'position Yfor fcausing the driving connection `of the sprocket wheel f7 Eto the shaft 6. A lato'h "structure 118 is mountedV upon the husking ibox 5 `and is employed for retaining the lever 14 in -itsfdotte'd l-ine position, see gFig. 2, 'which fposition `causes the sprocket wl-ieel 7 tto fbe disconnected from the `shaft 6. The 'chain tightening wheel 19 is =mountedupon the adjustable bracket 20 carried by the -lhusking box T5. By means `ofithis last menftioned structure, the sprocket l`chain 8 lmay be tensioned to any desired degree. -'iThe blower casing ll Yhas centrally projecting vtherefrom 'a discharge pipe 21 which terminates in a nozzle 22 "operatively associated with the husking box 5.

iln Figs. 3 to `l7 inclusive 'there iss'hown a slightlymodilied form of blower `whichin- 'cludes the blower casing 1112L yhaving vprojecting from one end thereof, said end being the intake end of the casing, a sprocket wheel 9a which is to be connected to the husking drive mechanism in the same manner as illustrated in Figs. l and 2 in connection with the first form of blower described. This casing 11a is formed with a discharge pipe 2la which is shown in Fig. 5 as having formed in its periphery an annular groove 23. Rotatably, adjustably mounted upon this grooved end of the pipe 21'a is an elbow 24 which has a plurality of adjustable screws 25 projecting into its bore and received within the groove 23 of the discharge pipe 21a, the screws 25 and groove 23 permitting the nozzle elbow 24 to be adjustably retained upon the pipe 21a.

In Figs. 3 and 6, the nozzle elbow 24 is illustrated as having formed on its inner end a ring gear 26 which constantly meshes with a gear 27 mounted upon the shaft 28 carried by the bracket bearing 29 which is suitably fastened to the casing 11a. This shaft 28 has mounted upon its opposite end a bevel gear 30 which meshes with a bevel gear 31 carried by the crank sha-ft 32 journaled in the bearing bracket 29. This crank shaft 32 is provided with a crank handle 33 by means of which the nozzle elbow 24 may be adjusted upo-n the discharge pipe 21.

The free end of the nozzle 24 is formed with the ,plurality of apertured ears 34A which have bolted thereto, by the bolts 35, a similar number of apertured ears 36 carried by the nozzle mouth 37 which has its free end 38 operativelyassociated with the husking box.

Pivotally mounted within the bore of the nozzle mouth 37 is a flap valve 39 which has mounted upon its supporting shaft an operating knob 40 by means of which the angularity of the iap valve 39 may be varied. For the purpose of retaining this flap valve in any of its desired adjusted positions, a gear 4l is mounted upon the supporting shaft of the flap valve 39 and has associated therewith a latch member 42 carried by the boss 43 on the nozzle mouth 37, as best-illus trated in Figs. 3 and 7. This latch 42 is spring pressed into operative relation with the gear 4l by the spring 44 and is further provided with an operating handle by means of which the latch 42 may be shifted against the tension of the spring 44 for disconnecting the gear 41.

It will now be understood that the nozzle elbow 24 and the nozzle mouth 37 may be adjusted in the direction of the arrows shown in F ig. 4 by operating the crank handle 33, shown in Fig. 3. This adjustability of these elements will permit the discharge end 38 of the nozzle mouth 37 to be varied in respect to the husking boX 5. To permit the active area of the nozzle mouth 37 to be varied, the flap valve 39 may be adjusted for increasing or decreasing the area of the space in the mouth 37 through which the blast of air is permitted to pass.

It is to be understood that the forms of this invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described the invention, I claim In a device of the type described, the com-V on said shaft, an operating crank journaled in said bracket, and a bevel gear on said crank meshing with the bevel gear of said shaft; a mouth fastened to said nozzle,

Vmeans for varying the active area of said mouth, said means including a flap valve, an operating knob connected to the valve, a. gear connected to the knob, and a spring pressed latch forengaging the gear to hold the valve in any adjusted position; and means for selectively connecting the blower to the husking mechanism drive. j

In testimony whereof I aiiix my signature.

GEORGE J. S'OUKUP.
